Specification forming part of Letters Patent No. 34,394, dated February11, 1862.

To all whom t may concern:

Be it known that I, JOHN ORITCHERSON, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and ImprovedRoller for Clothes-W'ringers; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, making a part of this specification, inwhich- Figure l is alongitudinal section of my improved roller, thesection being taken in the' line x of Fig. 2. Fig.- 2 is a transversesection of the same, the section being taken in the line y y of Fig. l.

Similar letters of reference indicate corresponding parts in the twofigures.

This improvement relates to that class of clothes-wringers which consistof two flexible or yielding rollers, between whichunder pressure and inmotion the clothes or other articles to be wrung are passed and therebydeprived of their moisture.

The invention consists in making the said rollers of disks of felt,having interposed thin metal disks to give firmness to the roller and toprevent the felt from slipping, the said disks being placed on apolygonal shaft and clamped between a stationary or fixed and a movablecollar.

To enable others skilled'in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a short shaft, which may be of wrought-iron or steel,having journal-bearings at its ends. On one end of this shaft, inside ofthe journal-bearing, is a collar b, which in the present instance isformed on the shaft, but which may be made separately and afterwardattached to the shaft in any suitable manner. The shaft inside of thiscollar and between it and the journal-bearing on the opposite end of theshaft is made square to receive the disks of felt and metal, which havesquare holes in them to correspond with the shaft.

B is a movable collar of brass or other suitable metal, which is fittedto have longitudinal movement on the shaftA and serves with the iixedcollar b to clamp the disks of felt and metal together. This movablecollar is secured when in the proper position on the shaft by a pin c,which is introduced outside of the collar through a hole passingtransversely through the shaft.

O O are disks of felt of which the roller is composed. These disks areof circular form with iiat sides and have a square hole made centrallythrough them to correspond With the shaft upon which they are placed.Placed on the shaft between these disks of felt are thin metal disks d,which may be of zinc or of any suitable material to give greaterfirmness to the roller, and also to give additional security against thedisks of felt slipping round on the shaft. These disks are made ofsmaller diameter than the felt disks to allow the surface of the rollerto yield.

The requisite number of felt disks being placed upon the shaft in themanner described to form a roller of the required length, the movablecollar B is placed over the end of the same and the felt compressedbetween it and the fixed collar in any suitable manner, ac-

cordingly as a hard or soft roller may be desired. The metal disksembedding themselves in the felt leave the surface of the roller smoothand unbroken. The movable collar is then secured on the shaft by a pinc, inserted through a hole in the shaft, as before described.

Instead of the movable collar being secured by a pin, it may have ascrew-thread cut in it to fit over a corresponding screw-thread cut onthe shaft, in which case the compression of the felt disks may beeffected by the screwthread of the movable collar without resorting toother means, only a metal disk should be placed outside of the felt forthe movable collar to work against, instead of allowing it to workagainst the felt, as it does when the pin is used.

The two rollers which constitute the wringer are made precisely alike,as also are their shafts, with the exception that one end of one shaftis made longer than the other and terminates in a square shank toreceive a Winch or crank, whereby a rotary motion is given to therollers, they being arranged in a stand in the usual manner. The clothesto be wrung are passed between these rollers while in motion. Theclothes, in consequence of the pressure to which they are subjected, areeffectually deprived of most of their moisture as they pass the centerof the rollers. The water, be-

As a new article of manufacture, a roller for clothes-Wringers,consisting of disks of felt C, with interposed disks of thin metal 0larranged on a polygonal shaft A and secured thereon in a compressed formby collars B b, the Whole operating in the manner and for the purpose.

substantially as described.
